Essentially this P0051 Toyota code means that the resistance of the heater circuit is lower than normal. In most cases, that resistance level must fall below 0.8 A to trigger the DTC code. Note, this code is very similar in nature to P0031 Toyota, P0032 Toyota, and P0052 ToyotaAn oxygen sensor has a heater element that allows it to quickly come up to 600°Fto produce accurate readings. The code P0032 is set by the PCM when it detects that the heater control circuit exceeded its high voltage limit.
Could be plugs, injectors, carbon buildup, etc. Quite likely simply changing it will fix the issue, but knowing more would certainly help. 4) EC = emission controls.
